All issues

Dear colleagues,
During the process of preparing, and considering the still aggravating circumstances of work and activities through most of 2022, as well as the fact that the number of received and peer-reviewed papers could not fulfill the condition for publication in accordance with the planned dates, this issue also faced certain difficulties of a technical nature in the course of its publication, and consequently the printing had to be delayed for some time.

Nevertheless, wishing to continue the publication, this issue of MAŠINSTVO offers you five papers from different thematic areas: comparative analysis of electricity consumption coverage
of a typical household in BiH for different geographical regions using photovoltaic panels with relevant techno-economic analysis; presentation of the programming process of milling processing and presentation of ESPRIT application possibilities through a realistic simulation of the process itself on the machine; implementation of 3D scanning and 3D printing technologies, which applications keep increasing in digitization, presentation and creation of replicas of various art pieces; an example of the use in high school education of a special NI Multisim software product used for modeling and simulating the operation of electronic circuits and digital electronic systems.

In order to present scientific-research and professional capacities, the journal follows new trends and practices in multidisciplinary areas.

The ‘Guidelines for Authors’ section provides basic instruction for preparing and writing papers, and we kindly invite all esteemed colleagues to take part and publish their scientific and professional research results in this journal, which is considered as a significant project of the Faculty of Mechanical Engineering of University of Zenica and gives the opportunity for presenting scientific research and professional research results from highlighted and related thematic areas, especially to our young colleagues from all universities and other related institutions.

In special sections, the tradition of presenting scientific-research and economic capacities continues.
Sincerely,
Fuad Hadžikadunić, Editor-in-Chief

PROGRAMMING OF MILLING OPERATIONS BY USING ESPRIT

Machining speed is one of the most important components in the production process, so it is necessary to use the most complete program package or software. Esprit is the ideal choice, because it is a CAD/CAM software in which it is possible to draw, model, program, and finally generate G-code for any machine tool. It is a very powerful, highperform...

3D DIGITALIZATION AND PRINTING OF A SCULPTURE FROM SMRIKE NATIONAL MONUMENT Josip Kačmarčik

3D scanning and 3D printing finds more and more application in digitalization, presentation and replicas making of different artworks. In this paper the capabilities of these technologies are represented on the example of a selected sculpture from Smrike national monument. Polygonal 3D model of the sculpture is made by using a manual 3D scanner. Us...

MATHEMATICAL AND NUMERICAL ANALYSIS OF THE RELATIONSHIP AMONG THE LOSCHMIDT CONSTANT, THE AVOGADRO CONSTANT, AND THE SPEED OF SOUND IN IDEAL AND REAL GASES AT STANDARD STATE

In this paper, a differential equation is derived relating to the relationship among the Loschmidt constant, the Avogadro constant, and the speed of sound in gases as a function of the thermodynamic properties of the gas (pressure, temperature, and volume). To confirm the validity of the derived equation, the ratio of the constants NL/NA and the de...
